Description
The present invention relates to a kind of electric connector, in more detail, this electric connector that the present invention relates to is suitable for being installed on the cable such as coaxial cable that is equipped with outer conductor.
As shown in Figure 6, comprise at the electric connector 50 of Japanese Utility Model patent application S59-17386 (on August 29th, 1985 open) and the disclosed routine of Japanese Utility Model patent application S59-166251 (on May 29th, 1986 disclosed) and to be connected cylinder 51 and 52, division formula anchor clamps 53,54, one joints 57 of a supporting mass and an insulator 58.The coaxial cable 100 that is fixed on the electric connector 50 comprises: inner wire 102 and an insulator 103 that an outer conductor 101, that is formed by the annular ripple contact tube is made of a contact tube.
In connecting cylinder 51, be provided with a link 100a of coaxial cable 100. Connect cylinder 51 and 52 and have flange 51a and 52a separately.Connecting between the cylinder 51 and 52, division formula anchor clamps 53 and supporting mass 54 are set.As shown in Figure 7, division formula anchor clamps 53 comprise a pair of semicircle division element 53a, 53a, and their two one side ends all are connected to each other together by a nylon tape and screw 56.
Referring to Fig. 6, on supporting mass 54 inner surfaces (right side), be provided with a supporting base 54a again, an end face of division formula anchor clamps 53 is installed among the supporting base 54a towards the inner surface of supporting mass 54.Outer conductor 101 is corrugated in the form of a ring, and one of them link 101a is radially outward expanding after passing connection cylinder 51, and clamped between the supporting base 54a of end face that divides formula anchor clamps 53 and supporting mass 54.
So, coaxial cable 100 adopts a kind of like this mode to be mechanically secured on the electric connector 50, promptly connect cylinder 51 and connect together by the screw (not shown) with 52a with 52 flange 51a, meanwhile, the end 101a of outer conductor 101 is clamped between division formula anchor clamps 53 and the supporting mass 54.Its result, the end 101a of outer conductor 101 is connected on the connection cylinder 52 by the mode of supporting mass 54 with energising.
The joint 57 of electric connector 50 is bearing in by insulator 58 on the inner surface of supporting mass 54 (left side), and insulator 58 splits into two circular-arc parts.The left inner surface of supporting mass 54 is provided with the supporting base 54b that is used for supporting insulator 58, insulator 58 again by with the cooperating supported joint 57 and clamp joint 57 of supporting mass 54 inner surfaces.
For the assembling mode of conventional electric connector 50 that above-described structure is described, coaxial cable 100 is packed in advance from an openend that connects cylinder 51 tube.Then, make the link 101a of the outer conductor 101 of the coaxial cable 100 of drawing from another openend that connects cylinder 51 keep outwards expanding, and on the inner peripheral surface of the link 102a of the inner wire 102 of coaxial cable 100 tap out, to form male thread portion 102a.After this, division formula anchor clamps 53 are fixed on the outer peripheral face of link 101a of outer conductor 101 of coaxial cable 100, and the link 101a of outer conductor 101 is clamped in the end face of division formula anchor clamps 53 and has between the supporting mass 54 right side inner surfaces of supporting base 54a.
The surface that connects cylinder 52 is coated with the conductance of silver coating (not shown) with outer conductor 101 these circuit on one side of guaranteeing coaxial cable 100.In addition, except being used as the inner peripheral surface of circuit of outer conductor 101 these one side, silver coating is also coated with the nickel coating (not shown), to reach etch-proof purpose.
Yet, with regard to conventional electric connector 50, supporting mass 54 only needs to be used to support division formula anchor clamps 53 and the insulator in electric coupler component 58, therefore, if consider to reduce the part count of electric connector, the cost of assembling work, the manufacturing cost and the electric connector weight of electric connector, cancellation supporting mass 54 then is desirable.Especially, because between connection cylinder 51 and 52 supporting mass 54 is set, the axial elongation of electric connector 50 is considered the miniaturization of electric connector, and it also is desired omitting supporting mass 54.
In addition, it is expensive being used to connect the split piece 53a that constitutes division formula anchor clamps 53 and the nylon tape of 53b, and needs a lot of time and work to be connected them.
